Look for a Uniform Shape Choose a watermelon that is symmetrical and has a smooth, rounded shape. Irregularities may indicate underdevelopment or uneven ripening.
Check for a Sugar Spot (Field Spot) The sugar spot, or "field spot," is the rough, brownish area where the watermelon rested on the ground while growing.
Tap It Tap the watermelon with your fingers and listen for a deep, hollow sound. This means the melon has a good amount of water content and is ripe. If the sound is dull, it may be under-ripe or overripe.
Examine the Skin A watermelon’s skin should be firm and glossy. Avoid melons with dull or wrinkled skin, which can be signs of age or dehydration.
Feel the Weight Pick up the watermelon and feel its weight. A ripe watermelon will feel heavy for its size, indicating that it’s full of water and juice. If it feels light, it may be dry and overripe.
Look for Sugar Crystals If you see sugar crystals around the stem area, it’s a good sign that the watermelon is sweet and ripe. These crystals appear when the sugars inside the melon have concentrated.
Consider the Season Watermelons are typically at their sweetest in the summer months, so purchasing one during peak season (June to August) can increase your chances of finding a delicious melon.
By testing and not guessing, you’ll have a much better chance of enjoying a sweet and juicy watermelon every time!
